20100185280 | ROTARY BLOOD PUMP AND CONTROL SYSTEM THEREFOR - A pump assembly and estimation and control system therefor, the pump adapted for continuous flow pumping of blood. In a particular form, the pump is a centrifugal pump wherein the impeller is entirely sealed within the pump housing and is exclusively hydrodynamically suspended therein against movement in three translational and two rotational degrees of freedom as the impeller rotates within the fluid urged by electromagnetic means external to the pump cavity. Hydrodynamic suspension is assisted by the impeller having deformities therein such as blades with surfaces tapered from the leading edges to the trailing edges of bottom and top surfaces thereof. | 07-22-2010 |
20100185043 | HEART ASSIST DEVICE, CANNULA AND FILTER THEREFOR - A cannula, such as an implantable cannula, for an implantable blood pump is disclosed. The cannula comprises a body having a bore extending between an inlet and an outlet for fluid communication therebetween. A filter is disposed in, on or at the body and arranged to filter blood clots from at least a portion of fluid passing through the body, and therefore into the blood pump. The cannula is preferably arranged to be mounted between a patient's left ventricle and an implantable blood pump. Also disclosed is a filter and a heart assist device, such as a blood pump, incorporating a filter to prevent blood clots from entering the blood pump. | 07-22-2010 |
20100036487 | Blood Pump With An Ultrasound Transducer - A blood pump including a ultrasonic sensor mounted in or on a blood contacting surface of said blood pump. The ultrasonic sensor measures blood velocity and reports information to a blood pump controller and wherein the ultrasonic sensor is directed to measure blood velocity in an inflow cannula connected to the blood pump. | 02-11-2010 |
20100028178 | Rotor Stability of a Rotary Pump - A rotary pump including an impeller rotatable within a housing. A load is imposed on the impeller as it rotates, in a direction that is substantially parallel to the axis of rotation and wherein the load stabilises the motion of the impeller. The load may be achieved by magnetically biasing the impeller. | 02-04-2010 |
20090155049 | ROTARY PUMP WITH EXCLUSIVELY HYDRODYNAMICALLY SUSPENDED IMPELLER - A pump assembly | 06-18-2009 |
20080221921 | METHOD OF CONDUCTING A CLINICAL TRIAL - Disclosed are methods of conducting and assessing the outcomes of a randomized controlled clinical trial. The method comprises the steps of: trialing, with respect to a first group of patients as an experimental group, an experimental treatment; and trialing, with respect to a second group of patients as a control group, at least first and second control therapies. The control therapies will have been previously validated or are a known standard of care. This method is described in relation to trialing and assessing implantable medical devices such as left ventricular assist devices (LVAD) but may be used for trialing and assessing other medical devices. | 09-11-2008 |
